Amit Mohanty · Answer

You can use the SHA512 class from the System.Security.Cryptography namespace. Here's an example of how you can generate a SHA-512 hash in ASP.NET: using System; using System.Security.Cryptography; using System.Text; public class Program { public static void Main() { string input = "Hello, World!"; string sha512Hash = ComputeSHA512Hash(input); Console.WriteLine("SHA-512 Hash: " + sha512Hash); } public static string ComputeSHA512Hash(string input) { using (SHA512 sha512 = SHA512.Create()) { byte[] inputBytes = Encoding.UTF8.GetBytes(input); byte[] hashBytes = sha512.ComputeHash(inputBytes); StringBuilder sb = new StringBuilder(); foreach (byte b in hashBytes) { sb.Append(b.ToString("x2")); // Convert each byte to a hexadecimal string } return sb.ToString(); } } } In this example, the ComputeSHA512Hash method takes an input string, converts it to a byte array using UTF-8 encoding, and then computes the SHA-512 hash using the SHA512.Create() method. The resulting hash is returned as a hexadecimal string representation.

In ASP.NET, you can generate the SHA512 hash using the System.Security.Cryptography namespace. please find an example of how you can generate the SHA512 hash in ASP.NET using System.Security.Cryptography; using System.Text; // ... public string GenerateSHA512Hash(string input) { using (SHA512 sha512 = SHA512.Create()) { byte[] inputBytes = Encoding.UTF8.GetBytes(input); byte[] hashBytes = sha512.ComputeHash(inputBytes); // Convert the byte array to a hexadecimal string StringBuilder sb = new StringBuilder(); foreach (byte b in hashBytes) { sb.Append(b.ToString("x2")); } return sb.ToString(); } } In the example above, the GenerateSHA512Hash the method accepts a string input and returns the SHA512 hash as a hexadecimal string. Here's how you can use the method: string input = "Hello, World!"; string sha512Hash = GenerateSHA512Hash(input); Console.WriteLine("SHA512 Hash: " + sha512Hash);

using System.Security.Cryptography; using System.Text; public string GenerateSHA512Hash(string input) { using (SHA512Managed sha512 = new SHA512Managed()) { byte[] bytes = Encoding.UTF8.GetBytes(input); byte[] hashBytes = sha512.ComputeHash(bytes); StringBuilder builder = new StringBuilder(); foreach (byte hashByte in hashBytes) { builder.Append(hashByte.ToString("x2")); } return builder.ToString(); } } string input = "Hello, World!"; string sha512Hash = GenerateSHA512Hash(input); Console.WriteLine(sha512Hash); The output of generating the SHA512 hash for the input "Hello, World!" using the provided code will be: 2ef7bde608ce5404e97d5f042f95f89f1c232871
